Research of meat samples cooling by immersion in single-phase and binary cooling medium

Abstract

The article considers the possibility of using a two-phase cooling medium (binary ice, in the foreign literature — ice slurry) for immersion cooling of hermetically packed food products. Experimental studies of heat transfer processes from cooled meat products to binary ice and single-phase liquid medium have been carried out. Based on the results obtained, the appropriateness of using binary ice for cooling hermetically packed meat has been assessed. The experimental data have been obtained for the first time and the comparative assessment of the heat transfer intensity from packaged meat to binary ice and single-phase liquid under identical conditions has been correctly carried out. The advantage of binary ice has been confirmed not only in terms of maintaining the temperature of the coolant (storage capacity), but also in terms of higher values of the heat transfer coefficient compared to single-phase liquid coolant when cooling sealed meat products. The data obtained can serve as a basis for the design and development of immersion cooling systems based on binary ice.
